samenstel i This `invention relates to oond'ense'rs; and

anfobject'thereof is to provi-de acondenser in whichH compressed gas isnfor'ced Afrom a compressorinto' theVl condenser. and subjected 5 to the action of air forced through condenser tubes of novel construction, whereby thegas isV cooled and condensed to liquid more elficiently and rapidly than by the use'of condensers of different construction.

Another object of the invention istoprovide a condenser embodying the novel construction and obtaining the advantages of the condenser herein disclosed.

Other objects will appear from the foll5 the accompanying drawing in which Fig. 1 is an end elevation of ama-chine consisting of a compressor and the present condenser. f Fig. 2 is a section. Y Y Y Fig. 3 is a view showing gearing for operating the fan by which cooling air is drawn through the condenser tubes. Y

Fig. 4 is an enlarged vertical sectional view of the condenser similar to Fig. 2. y Fig. 5'is a cross sectional view on the line 5-5ofFig.4.

`F ig. 6 is an elevationv of one ofV the'con'- The invention isshown in connection with a compressor `1 from which a pipe 2 conducts the compressed gas into a condenser casing 3 above the level 'of the liquid produced in the condenser casing as a result of cooling and condensing the gas. From the condenser the liquid passes through a pipe 4 to the coils, not shown, or other place of use, and thence is returned through a. larger pipe 'shown as surrounding fthe pipe 4 but not in communication with the condenser. From the pipe 5 the gas is conducted through lapipe 6 to the compressor and thence through lthe pipe 2 to the con-denser for repeated use. The tubes'7 of the condenser are .of novel construction, being ofserpentine or crooked formationas will be understood by reference to Fig. 6, with a circumferential flange or fin 8 at each bend. In this Way the cool air is prevented from passing ina straight line through the condenser tubes and all of the air is caused to contact with the walls of the., condenser tubes at' some Vpoint or another. The tubes and the ianges or yns 8 are thus cooledL and the gas delivered to the conlowing description, reference being made-toA view showing the condenser inl 14; 15925: 'senat no. segiaaf denser from the; 'compressor' is conde-used. t9 liquid; v: y The lowenrendsofjthecondenser tubes/ open through; the: bottomj wallgl 9s of the; Qondenser, and the upper endsof the tubes'open through the top wall 10 of the condenser. Air is admitted to the condenser through an' air/ inlet pipe 11 (Fig. 2) opening into a drum or chamber 12 into whichthe lower; ends of the condenser tubes open andl from which the air passes through thecondenser tubes to a chamber 13 above the, condenser. Froin the chamber'l the'air passes through an opening 14 to an outletpipe 15.'V`

rll'he speed of circulation and the passage 701 of air through the condenser is increased by an air propeller or fan device adjacent to thev outlet opening 14 and consisting offa number of blades 16 supported between arms 17 attached to a rotary shaft 18. The'shaft 18 extends through the condenserl through "a straight tube 19 and at its lower end has/a' pinion 20 (Fig. meshing with` a pinion 21 on a shaft- .22 driven by gearing'23 from a ,i shaft 24 operated by themotor 25 of the compressor. p l From the foregoingthe advantagesk obf vtained by use of my improved condenser are obvious as is the fact that the invention obtains all of its intended objects andpurposes in a very efficient manner. The condenser maybe constructed at comparatively low cost and assemble'dand used without diiculty, I do not .restrictmyself in'unes-y sential particulars7 but whatV Ipclaim `and desire to secure by Letters Patent isz`- v 1.
